The distance of tumor spread in the main pancreatic duct of an intraductal papillary-mucinous neoplasm: where to resect and how to predict it

摘要

Background The surgical decision regarding where to resect the pancreas is an important judgement that is directly linked to the surgical procedure. An appropriate surgical margin to resect intraductal papillary-mucinous neoplasm (IPMN) of the pancreas based on the distance of tumor spread (DTS) in the main pancreatic duct has not been adequately documented. We analyzed the appropriate surgical margin based on the DTS in the main pancreatic duct of IPMN and the positive rate at the pancreatic cut end margin.
